LANTERN.

SPECIFICATION forming part o f Letters Patent No. 594,790, datedNovember 30, 1897. Application filed March 2, 1897. Serial No. 625,755.(No model.)

To a/ZZ whom t may concern:

Be it known that I, -WILLIAM S. HAMM, of Chicago, in the county ofCook'and State of Illinois, have invented certain new and usefulImprovements in Lanterns, of which the following is a specication,reference being had to the accompanying drawings and to the numerals ofreference marked thereon.

My invention relates to an improvement in hand-lanterns such as are morecommonly used by conductors, brakemen, and railroadmen generally.

The objects of myinvention are to improve the construction of the upperportion of the device and to increase the illuminating qualities of thelantern, whereby a bright steady flame may be maintained and theliability of its being blownout or lextinguished by a sudden or quicklifting movement or by jar or shook is reduced to the minimum.

The first part of my invention has reference to a cap having awind-conefor deflecting the air that enters the outlet-openings in the 'cap whenthe lantern is exposed to strong winds and if not properly deflectedwill extinguish the flame or reduce its steadiness and illuminatingeffect. This feature of my'invention obviates this danger, the air beingcaused to pass over the top of the globe or chimney without injuriouslyaffecting the flame. All danger of extinguishment as the lantern issuddenly lifted is also prevented, the quick inrush of air, which underother constructions would pass into the globe or chimney, being brokenand deflected,

The second part of my invention relates to a simple Yand efficientdevice whereby the wind-cone, which by spring action presses upon andadjusts itself to the upper edge of the globe as the hinged cap isclosed down,

may be readily detached from the cap for purposes of cleaning orotherwise and as easily replaced. i

In the accompanying drawings, Figure lis an elevation of my improvedlantern. Fig. 2 is a section thereof on theline 2 2. Fig. 3 is aninterior view of the top. Figs. 4 to 10, inclusive, illustrate detailsand modifications.

Similar numerals of reference indicate similar parts in the respectivefigures.

In all forms of my invention as herein shown the base 1, lamp 2, globeor chimney 3, Wire guard-frame 4, and top or cap 5, except ashereinafter specified, may be of any construction at present found inapproved types of the lantern. v

Referring to Figs. l, 2, and 3, within the cap 5 is a wind cone,breaker, or delector 6, ad apted to slide vertically, its lower edgeembracing the globe or chimney 3 and holding the same firmly in place bymeans of a spiral spring 1l within the cap and bearing on the wind-cone6. The wind-cone consists of a shell of thin metal, its lower part beingcylindrical, while its upper vportion is of frustoconical shape, throughthe open top of which the products of Jcombustion pass into the cap 5and thence out of the lantern through the perforations l0, formed in thecap, as shown.

Riveted within the cone, near the top, and on opposite sides thereof,are two springarms 9 9, extending downwardly to a point near the bottom.Pins 9, one secured to the lower endof each spring-arm, pass throughperforations 13 lli, formed, respectively, in the wind-cone 6 and thecap 5. Finger-pieces 2, attached to the spring-arms, afford means forwithdrawing the pins from the perforations 14 in said cap when it isdesired to remove the wind-cone from the cap to clean it or for anyother purpose. If preferred, the finger-piece l2 may be formed of -acontinuous strip of metal having a loop in the center, as indicated indotted lines in Fig. 2 and in full lines in Fig. l0.

The openings 14 in the cap 5 are elongated, and in this form of myinvention stand in an inclined position, 'and the wind-cone, as thehinged cap is forced down and clasped to the upper edge of the wireguard, will be given not only an'upward movement as the spiral spring l1is compressed, but also a slight rotary movement, the pins 9a riding uptheinclined openings or slots 14.

In Fig. 4 the slotslli lin the cap for the pins 9a are arrangedvertically and the slight rotary movement just referred to is notoccasioned.

In Fig. 5 butone spring-arm 9 is shown, and consequently only one pin9a; but a stud or pin 9b is attached to the opposite side of thewind-cone, extending through its slot 14. in the cap. To remove thecone, the pin of the spring-arm must first be withdrawn from IOO itscap-slot 14, after which the cone will be ejected by the force of thespring, the pin 91 being removed from its slot 14 by this action. InFig. 6 the same construction is found, except that the pin 9b is securedto the cap instead of the cone, the latterv being slotted to receive thepin.

In the modification seen in Figs. 7 and 8 attached to the outside of thecap in the position shown is a fiat spring 9, its free end being turnedout to form a linger-catch and which has the pin 9a secured thereto,extending through a hole in the cap and the slot in the cone. A guard orstop l0 may be fastened to the cap to limit the outward movement of thespring. A stud 9b is oppositely secured to the inside of the cap and isadapted to enter the corresponding slot of the Windcone. Vhen the cap 5has been turned up, the spring 1l would force the wind-cone out of thecap but for the pin 9 and stud 9", which engage with the slots of thewind-cone. When the removal of the wind-cone is desired, the operatorretracts the spring 9, thus withdrawing the pin 9 from its engagementwith its cone-slot. This releases the windcone and allows the spring toforce it out of the cap. placing it in the cap and pushing it up untilthe proper slot of the cone engages with the stud 91. The spring 9c isthen bent outwardly, withdrawing the pin 9'. Now by pushing thewind-cone into place and releasing the free end of the spring the pin 9nwill enter its slot in the wind-cone and the latter will be secured inposition.

I sometimes dispense with a spring to force the wind-cone down upon thechimney, in which case, as illustrated in Figs. 9 and l0, the upper edgeof each of the inclined slots 14 is serrated to engage and hold one ofthe pins 9a when the wind-cone is turned to secure the globe or chimneyin place. It will be understood that by turning the cone it may bebrought to its proper vertical position with respect to the globe orvchimney and locked in such position by the engagement of the pins 9with the serrations.

Vhile my invention is here shown in con- The wind-cone is rea'djusted byit is to be understood that I do not wish to limit it to such, butreserve the right to use it with any style of lamp or lantern to whichit is applicable.

Having thus described my invention, I claim- I. In a lantern, thecombination of a cap, a removable Wind-cone adapted to move verticallytherein, and a spring-actuated pin arranged to enter a suitably-disposedopening in the cap and the wind-cone, substantially as described.

2. In a lantern, the combination of a cap having slots, as 14, awind-cone adapted to move vertically within the cap and be removedtherefrom, spring-actuated pins secured to the Wind-cone and arranged topass through openings in the cap, and through the slots 14,substantially as described.

3. In a lantern, the combination of a perforated cap having slots 14, awind cone adapted to move vertically within the cap, and be removedtherefrom, its upper end being above the perforations in the cap,springs secured to the wind-cone and provided with pins adapted to passthrough openings in the cap, and through the slots 14, and fingerpiecesfor actuating the spring, substantially as described.

4. In a lantern, the combination of a perforated cap, a removablewind-cone adapted to move vertically within the cap, springs secured atone end to the wind-cone, and provided with pins and finger-pieces, thesaid Vpins arranged to pass through the openings in the wind-cone andthe cap for retaining the wind-cone in place, means for forcing thewind-cone from the cap when the pins are With drawn from the openings,and a chimney upon which the wind-cone presses, substantially asdescribed.

In testimony whereof I have hereunto set my hand and'aflixed my seal, atthe said city,

of Chicago, this 15th day of February, 1897.
